Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed December 30, 1905. Serial No. 293,887-

To all whom it may concern.-

Be it known that we, WILLIAM R. BoN- NELL and JOHN F. CONRAD, citizens of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Drainage-Traps for Houses, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and'use the same.

This invention relates to drainage-traps for houses; and the object thereof is to provide an improved combination device of this class designed for use as a cellar-drain and backwater-trap and which is simple in construction and operation and which may be conveniently cleaned whenever necessary and also conveniently used wherever devices of this class are required.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of our improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a plan view of our improved trap; Fig. 2, a longitudinal section on the line 2 2 of Fig. 1; Fig. 3, a horizontal section on the line 3 3 of Fig. 2, and Fig. 4 a vertical section on the line 4 4 of Fig. 2.

In the practice of our invention we provide a trap of the class specified, which com rises a casing a, in the bottom of which is a 0' amber a and said casing is provided at the top thereof and at one side thereof with a tubular inlet extension (1 which forms a connection for the water pipe or pipes of a house, and at the side of the casing at opposite the tubular extension a and below the top of said casing is a tubular outlet extension a by which in practice the trap is connected with a sewer.

The casing a is provided witha vertical partition I), which extends below the bottom of the tubular extension a and between the lower end portion of which and the tubular extension a is an opening 6 which is adapt- .ed to be closed by a valve 6 hinged to the opening at the lower end of the passage 12 is plane passing through the casing a, the inclination of the valve being in the direction.

of the tubular extension a of said casing.

At the top of the passage 1) is a drainage inlet 0, closed by a perforated and removable cap 0 and within the inlet 0 is preferably placed a flexible and elastic seal device 0 similar in construction and operation to that described and claimed in Letters Patent of the United States, No. 803,979, granted to William R. Bonnell, one of the applicants herein, on November 7, 1905, and in the use of this trap the casing a is so placed that the drain-water from the cellar will pass downwardly through the inlet 0 and through the perforated and removable cap 0 which holds the elastic seal 0 in place.

Between the partition I) and the outlet extension of the casing a is provided with a large top opening at, closed by a removable cap d which is secured in place by screws and bolts d and d or in any desired manner, and the said cap 01 may also be packed in any desired way.

On the side of the partition 1) adjacent to the inlet extension a the casing a is provided in the top thereof with an inlet or opening e, formed by a tubular coupling extension e and in practice a Y-coupling e is detachably secured in the extension 6 said parts being preferably screw-threaded, and the Y-coupling e is closed by a removable cap a, and the branch 6 of said coupling is designed to serve as a connection for an air-supply pipe, and by removing the cap e the trap or the casing a thereof may becleaned at any time, and this operation may also be performed by raising or removing the cap (1 It will be understood that the partition I), which extends downwardly, centrally, and transversely of the casing 11 and especially the wall 12 of said partition which extends below the opening 6 into the bottom chamber a of the casing 01. in connection with the bottom portion of said casing, forms the trap proper, and water from the house pipe or pipes enters the trap in the direction of the arrow 00 and leaves in the direction of the arrow as", and in this operation the valve b is raised by the water as it passes through the trap. It will also be understood that the drain-water from the cellar flows into the trap through the passage 6 and is discharged with the water entering the trap, as indicated by the arrow no. If at any time and for any reason backwater from the sewer or branch pipes thereof should be forced backwardly into the trap in the direction indicated by the arrow y, the valve 1) would be at once closed and the backwater from the sewer would not flow backwardly through the trap and the overflow of the cellar will thus be prevented at alltimes, and it will also be understood that the valve l) is normally closed except when drain-water from the cellar is flowing downwardly through the passage 1).

This invention is simple in construction and operation and comparatively inexpensive, and changes in and modifications of the construction described may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described our invention, what We claim as new, and desire to secure by Letters Patent, is

' 1. A trap of the class described, comprising a casing provided at one side and at the top thereof with a tubular inlet and at the opposite side and below the top thereof with a tubular outlet, a partition extending trans versely across the casing and extending from the top thereof downwardly below the bot tom of the tubular outlet, a valve hinged at the bottom portion of said partition and adapted to close the connection betweenthe bottom of the casing and the tubular outlet, said casing being also provided in the top thereof and at the sides of the partition adjacent to the tubular inlet with a cellar-drain inlet, substantially as shown and described.

2. A trap of the class described, comprising a casing provided at one side and at the top thereof with a tubular inlet and at the opposite side and below the top thereof with a tubular outlet, a partition extending transversely across the casing and extending from the top thereof downwardly below the bottom oi the tubular outlet, a valve hinged at the bottom portion of said partition and adapted to close the connection between the bottom of the casing and the tubular outlet, said casing being also provided in the top thereof and at the side of the partition adjacent to the tubular inlet with a cellar-drain inlet, and a passage extending from the cellar-drain inlet to the bottom of said partition, substantially as shown and described.
